Physics The Greatest Magic

"Cancel." 

As if it were a pile of ash, the structured shadow spikes which had all been heading towards John, dispersed. 

The young boy's eyes widened as he saw this and without wasting another second, he shadow stepped away to get away from John. 

He shadow stepped quite far back to the end of the hall to assess the situation, but right as he did, he looked up to check on John's next move, only to not be able to find, nor sense him. 

Suddenly, he felt a presence appear behind him, and right as he did, he teleported behind that presence, grabbing on to it, and wrapping his arms around it to restrain it from behind. 

It was John, without shadow stepping away, John desperately grabbed on to the boy's hands to move it away, but the boy wouldn't let go. 

His grip was getting tighter and tighter, choking John out. John moved his hand to grab on to the boys face, trying to push it away, but the boy wouldn't budge. 

*Crack* 

The boy turned John's neck snapping it in the process. 

After this, he let go of John, and watched as John slowly fell on to the ground. 

"Tsk, Hahaha... I can't believe you had me scar-" 

The boy's eyes widened once more as the person who he had just killed ended up disappearing right in front of his eyes. No trace of darkness or nothing, it was as if John was never there. 

Upon reaching this conclusion, the boy turned around, and that was when he saw it. 

John had been standing right behind him. Confused, the boy hastily looked at the ground before looking back at John. 

"An illusion...?" The young boy asked 

Without replying John stared straight at the boy as he began walking closer. 

The boy tried to move back when all of the sudden, he realised that it wouldn't move. 

"!?" 

He tried to speak but couldn't speak either, It was as if another mysterious force was stopping him. 

John slowly walked to the boy as he muttered 

"Newton's 1st Law of motion." 

An object will remain in the same state of motion unless a resultant force acts on it. In other words, If an object is at rest, or not moving, then it will stay that way, until another force acts on it, causing it to move. 

And once it is in motion, it will remain at the same velocity, this was Newton's first law of motion. 

John created a force which balanced whichever force the boy could produce, causing him to be stationary as there was no force which could possibly act upon him to break through it. 

That was the concept behind 'Stop' or at least John's version. 

[Although, it's still weak compared to Zestari's.] John thought to himself 

"M...y... Body... What.... di...d-" 

Without waiting for the boy to finish, John suddenly vanished before reappearing in front of him. 

"I told you didn't I? that I would kill you." 

John said those words clearly straight at the boy's face as he stretched out his hand to grab on to him 

The boy couldn't move and only watched as John moved his hand closer and closer. The boy felt scared, weak and helpless, a feeling which he had long since forgotten. 

The instant John's hand touched his face, all of the boy's emotions burst out in anger, before he vanished. 

John curiously looked up only to see the boy standing around 10 meters away from John down the hall. 

His radiant dark hair, began to grow longer and glow brighter, as the dark gloves around his arm and dark shoes around his feet were reinforced. 

The boy's hair now reached his waist and his eyes now glowed a dark black. 

The boy slowly began to walk to John, seeing this, John muttered the spell once more 

"Stop." 

But the boy didn't stop, instead he disappeared, before reappearing right behind of John. 

Just like John, the boy had an emotionless gaze as he pulled out a dark scythe from thin air, before slashing it down at John. 

"Parry." Muttered John 

*Clang* 

As if being parried, the scythe was slightly pushed back along with the boy, but at the same time. 

*Voom* 

Half of John's body was erased. The void eating scythe which belonged to the young boy, scraped the space around John's body, causing half of it to end up being scraped. 

As John body fell to the ground, the boy noticed that no blood nor organs could be seen as darkness covered the area which had been cut off. 

Seeing this, the boy quickly turned to the right only to see that John was still alive and perfectly fine, as this happened, the other body the boy had just cut in half, had dispersed into darkness as if it were ash. 

"This wasn't the same as the other time... What did you do here?" The boy asked 

His voice no longer sounded like that of a kid like before, it sounded like there was something sinister hiding behind it. Almost like the voice of a grown man. 

"Don't worry, you'll be dead soon." Said John as he disappeared 

The instant, John disappeared, the boy also disappeared before reappearing near the end of the hall. 

*Clang* 

As he appeared, he swung his scythe parrying the swing from John which was aimed right at his beck. 

Right as he parried it, John vanished before appearing above him. Electricity passed through John's body as he noticed that a small part of his arm around his triceps had been scraped away. 

Seeing this, John activated [modero] before swinging both daggers diagonally at the back of the boy's head. 

*Slash* 

The instant his daggers landed on the back of the boy's head, he vanished before appearing above John. 

John wasn't surprised at all. He had already expected the boy to be able to shadow step faster than John could as the area was still covered in shadows. 

John was in his territory, but it didn't matter to him. 

As the boy swung scythe down at John, John swung his arm, throwing the little blood which had formed from the wound towards the boy. 

At the same time as this happened, the boy's swing was cut off as he was pushed by a mysterious force straight at the ceiling, just like before, 

Attract, a spell which worked Just like a magnet, an object which produced a magnetic field, and were attracted to each other's opposite poles. 

John was using electricity to turn himself into a magnet, on top of that, when they had their first interaction in the beginning of the fight, John added a part of his electricity on to the boy to charge the boy's particles, allowing him to reach the conditions necessary to make the boy a magnet. 

All John had to do, was change the charge, to either push the boy or attract him. 

Not only that, but there were other concepts behind the spell attract, just like there were other ways of replicating or using it. John hadn't realised this until now, and felt like an idiot for not having done so. 

Right before the boy landed on the ceiling, he turned his body, and landed on the ceiling with his feet, before leaping off of it, straight at John, with more power than the force John had unleashed on him. 

As he leapt straight at John and swung his scythe, a smirk was formed in front of John's face as he muttered 

"Black Hole." 

In that instant, the light in the room disappeared and the boy's eyes widened as he felt a chill go down his spine. 

A black sphere around his size was formed right in front of him, relentlessly pulling and dragging all the air and everything around it into it. 

Black hole, a move which John had hated himself for forgetting the concept of. After John's little to no contribution, in the recent attack which resulted in Serena having gotten kidnapped. 

He swore that he'd never let anything similar happen again, and so, he racked his brain as he searched for her, to see if he could remember any new strong concept which he could use. It was then that he remembered what had happened when he stopped the tower from falling. 

For a moment, just a single moment, he was able to create a distortion in the space which worked like a vacuum, and the was only the start. 

One by one, John began remembering concepts which he couldn't believe he had forgotten. 

One of them was the theory of the blackhole. Once mass had been compressed to an extreme point, an anomoly in the space would occur as it would start to suck everything into it, including light. 

Luckily for John, it wasn't just a theory, but only the beginning to the endless possibility of combinations of spells which would help him in the future, or so John believed. 

"Wha-!?"
